Pseudoaneurysm after sutureless repair of left ventricular free wall rupture: Sequential magnetic resonance imaging demonstration.

Sutureless repair is an effective procedure for acute left ventricular free wall rupture; however, it may be complicated with a left ventricular pseudoaneurysm during the late postoperative period. We present a case of a large ventricular pseudoaneurysm that occurred after the sutureless repair of an inferior myocardial infarction with oozing left ventricular free wall rupture. The patient underwent aneurysmectomy successfully. Serial magnetic resonance imaging (MRI) indicated that the necrotic left ventricular wall, which was covered by Teflon felt, had ruptured and developed a pseudoaneurysm. Therefore, after simple gluing for a left ventricular free wall rupture, patients should undergo careful follow-up evaluation for potential pseudoaneurysm. Moreover, early detection by MRI and prompt surgical repair of the complication are important in patients with left ventricular free wall rupture.
